Chronic Hyperthyroidism is a Frequent Illness in Cats, Affecting Mostly Elderly Cats

Thyroid glands have been found inside the neck of cats that serve an important part in controlling the body’s metabolism. The excess supply of thyroid hormone causes hyperthyroidism, which results in an acceleration in metabolism. This is a frequent illness in elderly cats. While hyperthyroidism causes the thyroid gland to expand, this is typically a benign alteration. Malignant thyroid hormone tumors are found in less than 2% of hyperthyroid instances in cats. Hyperthyroidism affects several organs, notably the heart. Feline hyperthyroidism is a prevalent illness that affects cats in their middle and senior years. Cats with hyperthyroidism have expanded thyroid glands along with both parts of their neck. An adenoma, that is nearly usually noncancerous, has been the most leading symptom of thyroid gland growth. Approximately 5 % of hypothyroidism suffering cats are under the age of 10.

Reasons for concern

However, though both sides of the thyroid are very often affected and have no anatomical link, it is believed that hyperthyroidism results from a circulating chemical. One of the most potential causes involves dietary variables. Packaged cat diets were actually developed in the 1960s, primarily on the eastern seaboard, where the illness first appeared in the 1970s. Canning fish, in particular, puts cats in greater danger.


Medicinal treatment, radioactive iodine therapy, surgical and nutritional therapy are indeed the four therapeutic alternatives for hyperthyroidism in cats. As with every medical therapy, there are pros and downsides. When it comes to treating hyperthyroidism in cats, there are several factors to consider, along with the patient’s general health and desire to take medication, as well as the owner’s capacity and desire to do so on a constant schedule. One can visit here to know about the treatments of hyperthyroidism in cats.


Anti-thyroid medications work by decreasing the thyroid gland’s ability to produce and secrete thyroid hormone. Hyperthyroidism cannot be cured with these drugs, although they can be managed for a short period or a long period of time. Medication has the benefit of being widely available and reasonably priced. Although some cats may have negative impacts from medicine, particularly vomiting, malnutrition and drowsiness, other cats may not experience any adverse effects. Certain cats and their owners may struggle to manage a multiple times oral dose schedule for the rest of their lives. Additionally, antithyroid medicines are accessible as skin-applying gel. For the most part, this epidermal gel’s efficacy is adequate.

Iodine-restricted diet

An iodine-restricted diet prescribed by your veterinarian is one way to treat hyperthyroidism in your cat. An elderly cat’s daily need for iodine is less than half of what this diet provides. The meal can be used to cure hyperthyroidism in cats that are not present in patients or achieve a high level, which seems to be the therapies of preference. As an additional option, nutritional management might be explored for cats whose guardians are unable to provide oral medicine, or for cats that have ill effects from other treatments available.
